Patch 4.3 PTR: Heart of the Aspects and other new mounts

Patch 4.3 has a new mount we're all very curious about, the Heart of the Aspects. What we're curious about is how we're going to get our grubby little mitts all over it. Is it a heroic Deathwing drop? Or do we get it for completing a raid wide meta-achievement? Is it for killing Deathwing without the aid of the Aspects, the way Mimiron's Head dropped in Wrath? That last one seems unlikely to me, with the way heroic difficulty is accomplished now, but I can't rule it out.

Also interesting to note is Experiment 12-B, also new in the most recent data push. What does he look like? Where does he come from? Is it for killing Ultraxion? Another possible meta-achievement mount, as we speculated the Life-Binder's Handmaiden could be? At this time, I have no idea -- but it's new and shiny and I'm sure we'll all want one.

We've included the video from MMO-Champion behind the cut, so you can get a look at the Heart of the Aspects mount in motion.
